UNITED STATES PATENT OFFICE- CURTAIN SUPPORT.

Application filed March 20, 1924. Serial No. 700,515.

This invention relates generally to supports for window curtains, moreespecially to supports constructed wholly of metal and consisting ofmounting brackets adapted to be secured at opposite sides of a windowframe, and a member, from which the curtains are hung, in the form of abar or rod with laterally-bentor bowed ends arranged to detachablyengage the mounting brackets aforesaid.

My invention has for its main object the provision in a-curtain supportof the kind referred to, of a simple form of interlock construction thatwill rigidly hold the bar or rod member normally against displacementrelative to the mounting brackets, and yet permit its ready and quickattachment to, or detachment from the brackets when hang- .ing orremoving the curtains.

Other objects and attendant advantages of this invention will be readilyapparent from the detailed description which follows, its scope beingclearly defined by the appended claims. V

In the drawings, Fig. I is a perspective View showing in completeassemblage a curtain support conveniently embodying my invention.

Fig. II is a view of the support assemblag in cross section and on alarger scale to show the details of the interlock between the curtainrod and the mounting brackets to better advantage.

Fig. III is an illustration similar to Fig. II showing an alternativeform of the in vention. v

Fig. IV shows another modification of which this invention is capable.

Fig. V is a perspective view of a mounting bracket modified for use witha curtain rod of circular or rounded cross section;

Fig. VI, a fragmentary view of the round rod adapted to be used with themounting bracket of Fig. V; and

Fig. VII, a face view of one of the rod ends. I i

A curtain support typical of my invention comprises, with referencefirst to Figs. I, II and III of the drawings, a pair of mountingbrackets 1 adapted tobe secured at opposite sides of a window frame tosustain the rod or bar 10 (upon which the curtain is'to be hung) throughengagement with its laterally bent or bowed ends.

.Confining attention for the time being to r the mounting brackets1,-these are exact duplicates of one another, each being formed from anelongated blank of stout'sheet metal with its central portion offset orraised asat 2 relative to the plane of its ends 3. The ends 3 arepierced as indicated at at for passage of screws or other convenientsecuring means 5. The ofiset or raised portion 2 of the bracket 1 ispunched or otherwise provided with elongated apertures or slots 6, 7that are aligned along the longitudinal medial of said bracket andcomparatively closely spaced as seen to the best advantage in Fig. II.

In the instance under present consideration, the rod 10 is shown asformed of relatively thin sheet metal fashioned, after approvedpractice, to channel formation with opposite longitudinaledgesretroverted as indicated at 11, the stiffening thus affordedrendering said rod amply rigid against sidewise fieXure. If lengthwiseadjustability should be desired, the rod 10 may be made in two parts orsections 10", 10 coupled in telescopic relation over a portion of theirlengths as indicated at 12 in F I. -The end of each laterally-bentextremity ofthe rod 10 is notched approximately centrally of its end asat 13, the top edge notched adjacent the end as at 14c, and the loweredge cut away as at 15 thereby. defining an upturned hook 16, a lug 17immediately below and in line with said hook and a shoulder 18beneathsaid lug. The notch 1 1 forming the bight of the hook 16 ispurposely given the acute angle profile shown to enable tilting oftherod in accordance with the dotted lines in FigII, suchprovisionfacilitating insertion of the hook into said aperture 6 of the mountingbracket 1. The lug 17 has its lower edge, sloped as indicated at 19 withthe result that it readily finds its way into. the aperture 7 of themounting bracket 1 when the rod 10 is swung downward after the hook 16is inserted in the In the alternative form shown in Fig TV the mountingbracket 1 has but sing e elongated longitudinal slot or aperture 6designed to receive the book 16 of the rod 10, the lug 17 of theprevious form being entirely dispensed with in this instance throughomission of the end notch 13, while the sloping edge 19 and the shoulder18 preserved to function in the capacity afore described. i

Fig. TV shows another modification, the hook 16 being in this caseturned downwardly. The lug 1? underlies the hook 16 as before but hereits upper edg instead of the lower edge, is sloped (in view of thereversed position of the hook to a. et or ease entry of the lug into theaperture 7, While it is to be noted the upper apertinc or slot 6 is madesufiiciently large to per t the hook 16 to be initially entered an dierod 10 manipulated to bring the lug 17 into register With the loweraperture or slot 7. The effectiveness of the last describedconstruction, it will be obvious, is on a direct par with the others. ineach" of the three instances thus far considered, a bar or red of solidrectanglar construction may of course, if it should be preferred, besubstituted in place of the channeled type shown.

In Figs. V, VI and V11, 1 have illustrated my invention as embodied in acurtain support involving the use of a rod 10 havinga rounded orcircular cross section. The profile configuration of the rod end will berecognized from Fig. V1 as identical to that characterizing thestructure of Fig. H, the upturned hook, the associated lug, and thecooperating shoulder being here identified respectively by the numerals16, 17 and 18 previously employed. By reason of the roundedcross-sectional configuration of the rod 10 in this instance, a slightalteration is required in the shape of the hook and lug receivingapertures 6, 7 in the offset 2 of the mounting bracket 1. In accord Withthis requirement, said apertures 6, 7 are made substantiallysemicircular in form to receive the hook 1.6 and the lug 17 with acomparatively close fit. lfdesired to ob tain the advantage oflightness, a tubular rod may obviously be used in place of the solid bardescribed.

Having thus described my invention, 1 claim:

1. In a curtain support of the type debed, a mounting bracket having araised ,sl portion provided with a transverse ire, and a rod havinglaterally-bent each said end being formed with a for engaging throughthe apertru'e in bracket and an aligned rigid- I lug, said lug beingnotchedout at the lower part to anord a supporting sh 1i forabutmentwith the outer face of the mounting bracket, and said hook and notclu iout part being, respectively, provided with opposedly inclined faces tofacilitate i sertion of the rod end into the mounting bracket.

2. in curtain support of the type described, a mounting bracket having araised central portion provided With a transverse opening; and rodhaving a laterally-bent end formed with an upturned hook notched out ofthe upper edge thereof, the bight of said hooks being of acute-angularprofile to permit tilting of the rod in engaging the hook in theaperture of the bracket, and a "jacent aligned rigidity maintaining lug,sa d lug being notched-out at the lower edge to affr d a thrustabutmentfor co-operation with the outer face ofthe aforesaid bracket andhaving its entry face opposedly inclined relative to the bightaforesaid.
